Definitely check to see if the door is balanced with the halfway open test. If the door is not balanced, then the opener will not work properly and could wear prematurely. Properly balanced doors require very little effort to open or close.
This summer, I serviced my neighbors metal building with 12' doors as both openers were on the fritz and the garage door guys never would show up for their appointments after 6 months of rescheduling. Doors were not balanced, one opener fried a belt, the other opener fried the receiver. Both had the torsion springs, so I sucked it up, cut some scrap rebar for spring tools and got everything balanced. Replaced failing parts, reprogrammed transmitters, and he was back in business a day later. He commented how quiet the openers were nowadays, before they hummed fairly loudly, he thought that I must have "tuned up" them electric drive motors
